Lower drum= 188 mm (7 13/32"); line entry height = 24 mm (15/16").Maximum holding power for high-tech line Sandblasted drums and ribs optimized for halyard and sheeting applications using small-diameter, high-strength line.Trim and ease sails quickly and easily Patented angle of ribs drives line wraps down when easing to keep them on area of drum that provides best control.Transfer high loads to the winch with fewer wraps.High-strength, lightweight Lightweight aluminum drum features an integrated skirt. High-strength composite roller and ball thrust bearings reduce friction under load. Load-carrying gears and pins are 17-4 PH stainless steel for strength, corrosion resistance.DO NOT use Harken equipment for human suspension unless product is specifically certified and labeled for such use.21'
